RADIO `BAT'JTERY`-CHARGJING CABINET.

Application led July 24, v1926. Serial No. 124,658.

This invention relates to a radio set consistine o'la combined stora ebatter and charger therefor and, therefore, Vmore par-V ticularly to theconstructionlof-,the case or container tor receiving the ,battervcharger as a unitary article ot manu acture in which the interior of thecase isdivided by a suitable partition into separate uprightcompartments tor receiving respectively the battery and charger. f Y yThe main object" to protect the battery and chargeragainst'accumulations of dust and other foreign matter and also againstContact with external objects and at the same time to allow freecirculation of air through both cells for Ventilating the battery cellfrom gases which may be liberated from the battery and at the same timeto ventilate the heated air from the charging cell produced by theenergizing of the charger thereby reducing the liability of escape ofthe gases from the battery to the chargin0r cell or the passage of theheat from the harging cell into the battery cell,` all of whichcontribute materially to the lite and etliciency of both the battery andthe charger. j

One of the specific objects is to construct the cover or lid in suchmanner as to extend across the entire area of the topl of both cells andat the same time to afford lateraleXit openings for the escape of gasesand heated an'. i

Other objects and usesrelatin to s ilic parts of the apparatus will beroug t out in the following description.

' In the drawings Figure l is a perspective view of a radio setembodying the various features of my invention. Y

yFigure 2 is an enlarged longitudinal vertical sectional view taken on`line 2 2, Figure 1.

Figure 3 is an enlarged transverse vertical sectional view taken on line3-3, Figure 1. Figure 4 is a horizontal sectional view taken in theplane of line [1 -4, Figure 2.

The case or container comprises a rectangular box -1-- and a lid orcover -2-, both of which are preferably made of wood or other insulatingmaterial treated in such manner as to render them acid-proof, Waterproofand weather-proof. the interior ofthe cell being divided by a transversepartition -3- into two compartments -4- and -l-5- for receivinga storagebattery -B- and.

top thereof.

and a charger -,-C- respectively.

The box 1 comprises a bottom wall --6-, opposite upright side walls -7-and opposite upright end Walls -8- permanently secured at theirjunctions onev to the other to form a rigid structure while thepartition 3- is permanently secured to the opposite side walls -7- andto the bottom wall --6--` at right angles thereto and extends somedistance above the upper edges ofthe side and endwalls as shown inFigure 2, said partition being located at one side of the transversecenter of the box so that the cell 411-- for receiving the battery issomewhat larger than the cell --5-- in which the charger i is located. Y

The lid --2- is of suflicient area to cover the upper ends of both otthe cells Jl-.- and 4H and comprises a top portion M9, cleats W10-q and-l1-- secured to the underside o'lE the top po`rtion---9----` and aInarginal flange -fl2- secured to the underside ot' the cleats --10--and -l il-- and projecting downwardly therefrom lo form with the topportion -9- an inverted box-like structure adaptedto rest upon the upperedges of thesides 7- and ends 8fwhen in operative positionbut capable ofbeing removed and replaced at will when desired. o

A bail --13- has its opposite endspivotally mounted in .suitablebearings .-14- on theopposite ends -8- ot the box near the upper edgesthereof and midway between the sides -7- and its intermediate portionprovided with a handle -15- by which the entire set may be carried fromplace to place when necessary.

The outer end wall -8- and opposite side walls of the cell h-5- areprovided with openings 16- for the circulation of air from the exteriorinto the charger cell --5-, said openings being preferably located nearthe bottom of the cell for the reception of the cooler air `from theoutside which upon entrance to the cell is heated and rises to the Thecleat -10 is located near one end of the top -9- while the cleats -l1-are arranged in longitudinally spaced relation to form a transversegroove -17- for receivingr the upper edge of the partition -3.

`The lower and upper edges of the flanges l2-- are parallel with eachother and with lOl the lower and upper faces of the top portion *9ewhich is spaced apart trom the upper edges of the tlaiiges -12- a.distance corresponding to the thickness of the cleats -l()- and l1-.

The cleats 10m and inner cleat 11'-H over the cell LL- are arranged inlongitudinally spaced relation to torni lengthwise openings -18- inopposite sides ot' the cover between the top portion -9- and upper edgesof the side flanges l2- to allow the escape of ventilation of any gasesor heatedY air which may tend 4to'accumulate in `the battery cell. H

The cleat 11- over the charger cell -5 is arranged in spaced relation tothe corresponding end flange form another vent opening -lextendingthrough opposite sides and the outer end of tliecover 2`V directly overthe cell *5i-- to allow the escape of heated air or gases which may tendto accumulate in said cell.

rflic partition -3- isV also provided with a lengtliwiseopening 20-between the upper edge thereof'and the upper edge ot' the box -ltopermit thel circulation of air and gases therethrough and thence throughthe openings -l8-v and -18- as may be necessary to tree the batterylcell from gases and also to reduce the liability of overheating of theair in the cell,--.

It will be noted that the cleats -11 are located in close proximity toopposite end faces of the partition -3- and serve to hold the cover -2-against endwise displacement. Y

The upper end of the partition -3- extends between the opposite sidewalls or flanges 12 of the cover -2- in close proximity thereto as shownin Figures 2 and 4 to hold the cover against accidental trans versedisplacement.

The space between the upper face of the lid -9- and overlying portion ofthe bail 12- so as to.

-13 is sulcient to allow the cover -Q- to be lifted above the upper edgeot the partition -3- and then removed or replaced laterally whendesired.

Operation.

W'hen the battery ;-B- and charger Ch are'installed in their respectivecoinpartineiits and thecover .9- is placed iii voperative positionV thegases escaping troni outfit is in operation the ventilation of bothcells is entirely automatic.V

The battery charger C- niay be of any standard construction but ispreferably arranged to auton'iatically keep the battery charged to asubstantially constant E. M. :fy

lVliat I claim is: f

In a device of the class described, a box, a cover for the box, atransverse partition dividing'tlie interior ofthe box intotworcoinpartiiients, a plurality of holes in the outer sides ofone ofsaid compartments located be-v low the horizontal center of Vthe box,'open spaces between the cover and the top of the outside walls of saidcompartment, open spaces between the cover and the lopposed outsideWalls of the other compartment7 andV a lengthwise opening vin the top ofthe partition constituting the only means of cominunt cation between thecoinpai'tn'ients- In witness whereof I have hereunto set in v 55 handthis 14th day Vof July, 1926.
